kmlcircles - draw circles around waypoints

kmlcircles [-a alpha] [-c color] [-r radius] -o outfile [infile...]

This program reads waypoints in CSV format and writes a KML file containing circles surrounding the waypoints at a specified distance.

-o outfile

KML filename to write to.

-a alpha

Alpha value for the circle fill, expressed as two hexadecimal digits from 00 (transparent) to ff (opaque). Default: 99.

-c color

Color for the circle fill and border, expressed in RGB using 6 hexadecimal digits. Default: ff0000 (red).

-r radius

Radius for the circles, in miles. Default: 0.1.

Any other arguments given on the command line are taken as filenames to read CSV data from. If none are specified, standard input will be used.

CSV format is expected to contain each waypoint on a line with commas separating the latitude, longitude, and name, in that order. Latitude and longitude are expected to be in decimal degree format.
